T0 all whom t may concern j Be it known that I, SHERIDAN D. SiM- MoNs, a citizen of the United States, and a resident of New York city, borough of the Bronx, county of the Bronx, and State of New York, have invented a new and 1mproved Rotary Engine, of which the f ollowing is a full, clear, Vand exact description.

My invention has for its object to provide a rotary engine having kblades extending through slots inV a rotatabledrum disposed in a casing and eccentric with a shaft, a portion of the casing being eccentric with an adjacent portion of the casing, and the shaft being provided with a crank disposed in the said adjacent portion of the casing..

Still other objects of the invention will appear in the following specification .in which the preferred formV of my invention is disclosed.

In the drawings similar reference characters refer to similar parts in all the views in which- Figure 1 is a sectional View on the line 1-1 of Fig. 2; Fig. 2 is a sectional view on the line 2-2 of Fig. 1; Fig. 8 is a view showing the drum with parts broken away to show the lugs to which'the radius rods are pivoted; and Fig. 4 is a sectional view on the line 4 4 of Fig. 3. Y

By referring to the drawings, it will be seen that a casing 5 is provided, this casing having a central portion 6 which is eccentric with reference to the side portion 7. Within the casing 5 there is a shaft 8 which has its central portion set off to forni a crank at 9 and which is disposed substantially concentric with the central portion 6 of the casing, the ends 10 of the shaft 8 being disposed substantially concentric with the sides 7 of the casing. Within the casing 5 there is disposed a drum 11, one side of which is disposed substantially at the inner side of the central portion 6 of the casing 5,

while the other side and the ends of the drum are disposedsubstantially at the inner sides at the sidesY 7 of the casing. In Fig. 2 of the drawings it will be seen that the top of the drum 11 is disposed adjacent the top of the central portion 6 of the casing 5V and that the sides at the bottom of the drum 11 are disposed adjacent the bottom of the sides 7 vof the casing. j j 3,

At the sides 11a of the 11 there are horizontally disposed slots 12 and in the central portion 11b of the drum 11 there are slots 13, blades 14 being disposed through the slots 12 and through the slots 18, the blades 14 extending to points adjacent the casing 5. The blades 14 are pivoted to radius rods 15 which are fulcrumed by pins 16 to the lugs 17 which extend inwardly from the drinn, the blades 14 being curved substantially concentric with the pins 16. The blades 14 are also connected with the shaft by means of the links 18. is best shown in Fig. 2 of the drawings, the links 18 are disposed between the arms 15a of the radius rods 15, the lugs 14a of the biades 14 Vbeing' disposed at the outer side of the arms 15a and a pin 19 beingl disposed through orices in the lugs 14a in the arms 15a and in the links 18, the links 18 having arms 20 which are mounted on the shaft 8, the arms 2O which are connected with each of the blades 14, being disposed at the sides of arms on the links 18 which are connected with blades adjacent the first mentioned blades.

By referring to Fig. 1 of the drawings it will be seen that steam or other gas under pressure may be introduced in the casing at the points 21, 22 and 28 through the pipe 24 and the branches 25, the communication between the pipe 24 and the branches 25 being controlled by valves 2G. it the other side Vof the casing there are pipes 27 which have branches 28 communicating with the interior of the ends 7 of the casing, the communication between the branches 28 and the pipes 27, being controlled by the valves 29. lThis construction is provided so that the steam or other gas under pressure may be introduced into the left hand portions of the ends 7 of the casing as shown in Fig. 1, this steam Vor other gas under pressure acting against the blades 14 to rotate the blades 14 and with it the drum 11 in the casing. The steam or other gas under pressure is introduced into the central portion 6 of the casing by the pipe 80 and the branches 81, the communication between the pipe 30 and the branches 81 being controlled by the valvesz32. In this way with the rotation 1 of the drum the sides of the drum will be acted on bythe steam or other gas under pressure when moving at the left hand poi'- tion, the top and right hand portion of the casing Vwhile the blades 14 on the central j portion of the drum will be acted on by. the steam during their movement at the right hand portion, the lower portion and the left hand portion of the casing. All the blades 14 are mounted on the drum and on the shaft in the manner which has been described. The steam or other gas under pressure which acts against the blades 14 which move the ends 7 oi the casing 5 is exhausted through the branches 28 of the pipe 27 and the steam which acts on the blades 14 which move in the central portion 6 of the casing is exhausted at the branches 33 of the pipe 34, tliefcommunication between the branches 33 and the pipe 34 being controlled by the valves 35.

it will be understood that the top or the central portion of the drum ll will be disposed adjacent the top of the casing 5 While at the bottom the ends of the drum will be disposed adjacent the bottom of the ends 7 oi' the casing. ln this way the drum will be supported during its rotation.

As best shown in F ig. 4 of the drawings one end of the drum is provided with spokes 36 which have a bearing` 37 in which a crank 38Yon the shaft 9 is journaled, there being a cutaway portion 39 in the hub to which the spokes 36 are secured for the free movement ofthe end of the shaft l() at the crank 38. The hub 40 to which the spokes 36 are secured, is journaled in a bearing 4l in the end 42 oi the casing and this hub 40 has a recessedportion 43 for receiving an angular or other member 44 'for rotating the said angular or other member 44 with the rotation of-the drum ll. lThe drum l1 has annular recesses 45 which face the recesses 46 in the casing 5, packing rings 47 being disposed in these recesses to prevent the steam between the ends 7 and the drumV ll from moving to the central portion G of the casing.

The end 4S of the shaft is held against rotation in its bearing 49 by the pin 50.
